This invention is a novel washing powder intended for use in connection with either hot 'or cold water for the purpose of washing clothes, dishes and other articles. The

object of the invention is to PIOVIdO a simple and inexpensive compound, one whlch is easily fabricatedand packaged and one which, when used,.will be readily dissolved,

- producing an abundant quantity of suds and 10 at the same time softening the water, cutting the grease and dissolving and hxiviating the dirt. Another object of the invention is to provide a compound embodying these advantageous characteristics whlch will be the least harmful to the hands and also the fabrics or cloths being cleansed.

With these various objects in view my invention consists broadly in providing a washing powder comprising neutral tallow soap, tri sodium phosphate, sal soda andbicarbonate of soda and Glaubers salt.

The invention consists also in certain details hereinafter fully described and set forth in the appended claim.

In compounding a washing powder in accordance with my invention I employ substantially twenty parts by weight of neutral tallow soap which constitutes the soapy base of the compound. I also employ substan tially twenty parts by weight of tri sodium phosphate, this ingredient serving to soften the water without precipitation and also serving as a detergent and grease solvent. I use about forty parts by weight of soda, that is'a mixture of substantially equal parts of sal soda and bicarbonate of soda. This soda aiding the compound both as a detergentand as a grease solvent. y

In combination with the preceding ingredients I employ about twenty parts by weight of Glaubers salt which has a remarkable action as a dirt solvent and particularly as bringing about the action of lixiviation,

of course, be understood that there Application fled Kay 29, 1922. Serial no. 564,583.

inasmuch as the dirt and grease are readily separated from the fibrous or cellular portions of the cloths or fabrics and brought to the surface where they are immediately dissolved and removed.

While I have specified the various ingredients in the proportions specified it will,

may be variations in either direction so lon as the general proportions are retained, that is, I prefer to employ substantially 1 equal parts of the neutral tallow soap, tri sodium phosphate. and Glaubers salt and about double the-quantity of soda.

These proportions I have found to combine excellently to provide a washing powder which readily dissolves, producing an 0 abundance of suds immediately and through the medium of the various ingredients any and all kinds of water is softened, the grease is cut, and all varieties of dirt are dissolved and lixiviated.

In compounding the powder, the ingredients, in substantially the proportions set forth, are ground into a fine powder, and this powder I prefer to treat with a limited amount of moisture either in the form of steam or water so that the powder is transformed to a somewhat cementitious condition. This compound thus moistened may then be repulverized if desired and is then ready for packing.

Having thus described my invention, what I claim is:

A washing powder comprising: {g if lf Neutral tallow soap "s 20 Tri sodium phosphate 2O Sal soda 20 Bicarbonate soda -l 20 Glaubers salt 20 In testimony whereof, I hereunto aflix my signature.
